The closest I get to old radio programs is my annual viewing of the BEST Christmas movie ever, A Christmas Story. For those that don't know, it was written and narrated by Jean "Shep" Shepherd, a famous radio and TV personality from the 40s and 50s who, funny enough, got his start in Cincinnati, Ohio.
The whole movie plays out like a radio show with so many great scenes that hit you right in the nostalgia muscle. Here's one of my faves..
"It's a Clinkerrrrr!!!!"
"In the heat of battle, my father wove a tapestry of obscenity that, as far as we know, is still hanging in space over Lake Michigan"
Classic...
Here's the original radio show for anyone interested....
